0.075% Accuracy RS485 Protocol Pressure Transmitter
0.075% Accuracy RS485 Protocol Pressure Transmitter Description:
0.075% Accuracy RS485 Protocol Pressure Transmitter is an intelligent field
instrument in accordance with RS485 protocol. The original imported diaphragm is designed with a
microprocessor and a RS485 communication circuit. It can communicate bidirectional with any host
computer software supporting RS485 communication protocol or 268,275 hand-operated devices
that conform to RS485 communication protocol. With 5 bits intelligent digital liquid crystal display,
the differential pressure / pressure value, output current value and output percentage value can be
displayed on the spot. The debugging is very convenient, and the digital and intelligent functions of
the transmitter are realized. And with the traditional simulation input The output signal is
compatible so that the exchange with the analog table can be achieved without changing the control
system.
